Abstract
The utility model discloses a filling type stop valve, which is composed of a valve body, a sealing ring for the valve body, a valve clack, a valve rod, a hand wheel, etc. The utility model is characterized in that the clearance between the valve rod and the valve cover is provided with a filling chamber, and the inside of the filling chamber is filled with ink filler; the valve cover is provided with a filling hole, and the filling hole is provided with a fastening screw in a screwing way. The utility model has the advantages of simple structure, small size, good sealing performance, no leakage, convenient operation, no need of maintenance, etc.
Description
The utility model relates to a kind of filling type stop valve, and what it can be used as industry and the water of civil building, vapour, oily medium transmission pipeline blocks, connects valve.
The employed stop valve of present various pipeline, gap location at valve rod and valve gap adopts packing seal usually, must frequently change because filler is aging easily, thereby increased maintenance load, especially for the valve that is in the hot operation state in the heating pipeline, under the situation of temperature 〉=250 ℃, can not rest maintenance, after can only waiting until the heating end cycle, just can carry out repair and replacement work, cause the very big waste of the energy and water resources.
The purpose of this utility model provides a kind of good seal performance, on seal the filling type stop valve of Never-leakage.
Filling type stop valve described in the utility model, it comprises valve body 1, valve seals 2, flap 3, valve rod 5, valve gap 7 and handwheel 8, wherein is equipped with sealing gasket 12 between valve body 1 and the valve gap 7, tightens together with connecting bolt 4; Stem Mut 9 is fixed in the valve gap 7, screw in valve rod 5 by trapezoidal thread, in valve rod 5 bottoms flap 3 is housed, handwheel 8 is enclosed within valve rod 5 upper ends, it is characterized in that: the gap location at valve rod 5 and valve gap 7 is provided with filler chamber 6, annotates in this filler chamber to be filled with powder China ink filler, has notes filling perforation 11 and communicate with filler chamber 6 on valve gap 7, annotate in the filling perforation 11 and be screwed with tight state screw 10, seal.When rotating handwheel 8, the flap 3 that drives the bottom by valve rod 5 moves up and down, and forms sealing pair with the seal ring 2 that is embedded in the valve body, finishes opening and closing of valve; The last sealing of valve then is toward realizing by the filler chamber's 6 mesohigh filling powders China ink filler that is located at valve gap 7 and valve rod 5 gap locations.
The utlity model has following major advantage:
1. the high pressure packing formula is adopted in the sealing of going up of valve, and good seal performance is forever non-leakage.
2. cancel the correlated parts of sealing configuration on the old-fashioned stop valve such as Gland, bolt, simplify product structure, reduce the product height.
3. the saving raw material reduce cost, and techno-economic effect is remarkable.
4. easy and simple to handle, need not keep in repair, be user-friendly to.
Description of drawings:
Accompanying drawing is this filling type stop valve structure schematic representation.
Below structure of the present utility model and enforcement are described further:
The filling type stop valve is made up of parts such as valve body 1, valve seals 2, flap 3, connecting bolt 4, valve rod 5, filler chamber 6, valve gap 7 and handwheels 8, its assembly process is at first Stem Mut 9 to be fixed in the valve gap 7, screw in valve rod 5 by trapezoidal thread, fill out powder China ink filler by annotating filling perforation 11 toward filler chamber's 6 mesohighs notes afterwards, lock with screw 10 after reaching rated pressure, to guarantee the top seal of valve; The flap 3 of packing in the lower end of valve rod 5 is again fixed with jackscrew, finishes assembled.
Mouth is inlayed valve seals 2 in the medium channel of valve body 1, and sealing gasket 12 is placed on the upper flange plane, then aforementioned components is packed in the valve pocket by valve body 1 top, with connecting bolt 4 valve gap 7 and valve body 1 is linked together; Utilize taper connection to be inserted in handwheel 8 on valve rod 5 tops at last, fastening with nut, form the valve complete machine.
